My founder #53 is sitting with both of your cars at the factory. Same deal- in production in December, and was told delivery mid Jan, but certainly no later than end of Jan. Now it's end of a Feb or the first week of March.
Clearly Tesla fixed the issue on the production line that caused the problem that has our cars in purgatory waiting for manual correction. I wish Tesla would rebuild our cars and give themselves whatever time they needed to fix the early builds. Making some of your best customers wait, especially the sigs who paid years ago for the privilege of an early car, while you deliver production cars feels very wrong. Heck, I paid for the car in full based on the expectation of a January delivery.
/annoyed but trying to remain patient.
